#1 Rostral dorsum not separated from frons by strong transverse impression [fig.1]. Eyes situated significantly lower than surface of frons. Elytral intervals with divided small scales. Median lobe of aedeagus weakly sclerotized, before apex with lobes or at least their tracks. Apophyses about three times as long as median lobe. Manubrium of tegmen clearly swollen and curved at apex. Endophallus with one spiculiform sclerite at apex and with areas of small thorns at almost all surface. Subgenus Eurosphalmus s.str.

-- Rostral dorsum separated from frons by more or less strong transverse impression [fig.2]. Eyes situated very close to surface of frons. Elytral intervals without divided small scales. Median lobe of aedeagus strongly sclerotized and evenly narrowed to apex and sharpened at end, without any tracks of lobes. Apophyses about two times as long as median lobe. Manubrium of tegmen thin or thick but always equally wide at all extent, not curved at apex. Endophallus with very large sclerites and areas of small teeth in basal half. Subgenus Rhinomiamima Yunakov & Nadein, 2006

#3 Habitus [fig.3]. Antennae thin and long (scape at base half thin, then sharply widened to apex [fig.4]), eyes flattened, pronotum evenly convex at sides. ♂ metatibia with strong cut [fig.5]. Body scale cover: setae on elytra distinctly wider and stronger inclined, widened to apex, rounded at end, close-fitting scales on elytral intervals denser [fig.6]. Aedoeagus [fig.7]. Spermatheka [fig.8].

#5 Habitus [fig.2]. Antennae thick, scape distinctly curved [fig.22]. Rostral dorsum wider, separated from frons by weakly developed transverse impression. Lower surface of rostrum and gular area of head make obtuse angle. Pronotum strongly transverse (ratio of width to length = 1.16-1.40), front margin of 1st ventrite concave [fig.23], ♂ anal ventrite more convex and wider. Aedeagus larger with weakly sharpened elongated plate-shaped tip of median lobe [fig.24]. Spermatheka [fig.25].

-- Habitus [fig.26]. Antennae thinner, scape almost straight [fig.27]. Rostral dorsum narrow, separated from frons by strong transverse lowering. Lower surface of rostrum and gular area of head make almost right angle. Pronotum weakly transverse (ratio of width to length =1.1), front margin of 1st ventrite straight [fig.28], ♂ anal ventrite weakly convex and wide. Aedeagus smaller, with strongly sharpened elongated tip of median lobe [fig.29].
